This is the second part to my Vitruvian Man Activity. Students would have already gathered data on themselves to then analyze (first FREE activity in my store). They measured their height, armspan, and handspan to investigate a hypotheses that 1) the length of a man's outstretched arms is equal to his height and 2) the length of a man's hand is one tenth of his height.
I've used this product in both my AP Statistics and Statistics classes. I usually have enough time to do this and begin the analysis on the same day (50 minute class periods) and then finish the analysis in class the next day.
For this analysis, my answer key is NOT included because it really depends on the data that your students get. For my Statistics class, I've used this as a guided activity in class; for my AP Statistics class, I've talked through some of the main points but they would be able to do most of it on their own.
The analysis includes graphing by hand, creating a line of best fit by hand, creating a LSRL on Excel (I do this for them in class), interpreting slope and y-intercept in context, making predictions using the LSRL, finding the LSRL by hand, and finding the correlation coefficient by hand (with the help of a graphing calculator).
